We are going to Lapland this December - me, DH and 2 DC. I've never been somewhere so far north, and I'm not sure what to wear for travel or to pack. We are going with TUI for 3 nights and they are supposedly providing thermal snow suits and boots. Is anyone done this trip with TUI previously able to advise? How many layers will be needed under snow suits? What did you wear for travel that will be warm enough when we get there without cooking on the way?
